Find LCM of 231,235,811,690,460 with Prime Factorization
| 2 | 231, 235, 811, 690, 460 |
| 3 | 231, 235, 811, 345, 230 |
| 5 | 77, 235, 811, 115, 230 |
| 23 | 77, 47, 811, 23, 46 |
| 77, 47, 811, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 77 x 47 x 811 x 1 x 2 = 4050312420
Therefore, the lowest common multiple of 231,235,811,690,460 is 4050312420.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
231 x 235 x 811 x 690 x 460 = 13973577849000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
231 : 1, 3, 7, 11, 21, 33, 77, 231
235 : 1, 5, 47, 235
811 : 1, 811
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,235,811,690,460, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
235:5x 47
811:811
690:2x 3x 5x 23
460:2x 2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 23 = 3450
Therefore, the value for common factors is 3450.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 13973577849000/(1x3450)
LCM = 13973577849000/3450
LCM = 4050312420
Thus, we can understand that the LCM of 231,235,811,690,460 is 4050312420.
